You wouldn't invest
without testing first.
Every trading idea feels brilliant until the market proves otherwise. The difference between experienced traders and everyone else? They test before they risk.
Seasonality360 is backtesting software that lets you validate any recurring market pattern  annual, monthly, or intraday  across 20+ years of real data. Staircase equity curves, floating equity, drawdown analysis, and 15+ professional metrics. Not a toy. Not a chart overlay. A proper validation engine.
Because "I think this works" is not a strategy. "I tested this on 20 years of data and here are the numbers"  that is.
Watch the workflow before exploring the use case: discovery, validation, and execution planning in one clear process.
Built for traders who do their homework
Whether you're a solo researcher, a prop firm trader, or a systematic strategist  if you need evidence before execution, this is your tool.
Independent Researchers
You study market behavior before you trade it. You want to know if a pattern is real or noise. You need data, not opinions. The backtesting engine gives you 20 years of evidence in seconds.
Prop Firm Traders
You operate under strict risk limits. Every trade needs a documented reason. You can't afford to guess. Filter by max drawdown, backtest with TP/SL, build a strategy portfolio that stays within your constraints.
Systematic Traders
You build rules-based strategies and need to test them rigorously. Define entry windows, exit windows, and risk parameters. Get standardized metrics to compare strategy variants objectively.
Why most backtesting tools give you false confidence
A single equity line going up is not validation. Here's what's missing from the tools you've tried.
One line, no context
Most backtesting software shows a smooth equity curve with zero visibility into what happened during each trade. No max rise, no max drop, no floating equity. You can't tell if the strategy was underwater for weeks before recovering.
No year-by-year breakdown
An average over 20 years hides everything. Was it profitable every year, or did one outlier year carry the entire result? Without annual consistency data, you're trusting a number you can't verify.
Drawdowns are hidden
Realized drawdown and floating drawdown are different things. One shows closed-trade losses; the other shows how deep you'd have been underwater during open positions. Most tools show neither properly.
Missing the metrics that matter
Win rate alone means nothing without profit factor, expectancy, and Sortino. A strategy with 80% win rate and 10:1 risk-reward on losses is a losing strategy. You need the full picture.
The difference between guessing and knowing
Without proper backtesting
- Single equity line  no context on intra-trade risk
- No year-by-year breakdown  one outlier year hides the truth
- No floating equity  can't see how deep you'd be underwater
- Win rate alone  no profit factor, no Sharpe, no expectancy
- Cherry-picked timeframes that flatter the result
- No trade-by-trade max rise / max drop visibility
With Seasonality360
- Staircase equity + floating equity overlay  full visibility
- Year-by-year trade list  see if the edge is consistent or one-off
- Realized AND floating drawdown  know worst-case intra-trade risk
- 15+ professional metrics  Sharpe, Sortino, PF, Expectancy, and more
- 20+ years of un-cherrypicked real market data
- Max rise and max drop per trade  full intra-trade transparency
This is what proper validation looks like
Not a screenshot. Not a single number. A complete analytics output with staircase equity, floating equity overlay, drawdown timeline, and year-by-year trade history.
| Year | Entry | Exit | Entry $ | Exit $ | Max Rise | Max Drop | P&L | P&L % |
|---|---|---|---|---|---|---|---|---|
| 2020 | 23/06 | 31/07 | $91.66 | $106.26 | +15.93% | -3.58% | $14.60 | +15.93% |

This is the standard output of every backtest you run on Seasonality360. Not a premium feature. Not locked behind a tier. Every test, every time  the complete picture.
From idea to validated strategy in 4 steps
Pick any asset
Forex, stocks, crypto, indices, commodities. Choose the market you want to test. Any symbol, any asset class.
Define a time window
Annual, monthly, or intraday. Set the entry date and exit date  the recurring calendar window you want to validate.
Run the backtest
One click. Full equity curve, floating equity, 15+ metrics, trade-by-trade history with max rise and max drop per trade.
Decide with data
Save the result, add it to a portfolio, set alerts for the next trigger. Or discard it and test the next idea. Evidence over intuition.
How many trading ideas have you actually tested?
Most traders have 5-10 strategy ideas and have properly backtested exactly zero of them. In 30 seconds, you can validate any recurring pattern with 20 years of data.
What makes this backtesting software different
Staircase equity + floating equity
See both closed-trade equity and intra-trade fluctuations. Know exactly how deep you'd have been underwater during open positions  not just the final P&L.
20+ years of real market data
Not simulated. Not interpolated. Actual daily and intraday price data across forex, stocks, crypto, and commodities. No cherry-picked timeframes.
15+ professional-grade metrics
Sharpe, Sortino, Profit Factor, Expectancy, Max Drawdown (realized and floating), consecutive wins/losses, annual volatility. The numbers a serious trader needs.
Screener → Backtest → Portfolio
Don't just test one idea. Scan thousands of patterns, validate the best ones, combine them into a diversified portfolio with aggregate metrics.
What happens after the backtest?
Testing is step one. Here's the complete workflow from idea to execution.
Save to Portfolio
Add your best backtested patterns to a portfolio. See the aggregate equity curve, combined drawdown, and how your strategies correlate with each other. Build a diversified approach, not isolated bets.
Set Alerts
When a validated pattern's entry window approaches, get notified via Telegram, push, or email. Execute only the strategies you've personally researched and tested  no blind signals.
Add Notes & Memos
Attach research notes to any backtest. Document your reasoning, flag concerns, track refinements over time. Build an institutional-quality research journal around your discoveries.
One backtesting engine. Every market.
Forex
Test intraday windows on EUR/USD, session patterns on GBP/JPY, monthly edges on USD/CHF. 15+ years of tick data.
Equities
Annual rallies, pre-earnings drift, sector rotation. 20+ years on AAPL, MSFT, TSLA, SPY, and more.
Crypto
BTC monthly cycles, ETH quarterly patterns, altcoin calendar edges. Validated with the same rigor as traditional assets.
Commodities
Gold seasonal windows, oil harvest cycles, agricultural calendar patterns. Deep historical data for every commodity class.
Why not just use a spreadsheet?
Some traders try to build backtests in Excel or Google Sheets. It works  for about the first 3 trades. Then you realize you need to download 20 years of daily data, handle splits and dividends, calculate floating equity per trade, compute Sharpe and Sortino ratios, track max rise and max drop per trade, and build a staircase equity curve. That's not a spreadsheet. That's a software project.
Others use Pine Script on TradingView. It's powerful  if you code. And if you only need indicator-based strategies. For calendar-based patterns (buy on June 23, sell on August 1, every year for 20 years), Pine Script is the wrong tool. You'd need to write significant custom logic, and you still wouldn't get floating equity, staircase charts, or year-by-year trade transparency.
Seasonality360 does all of this in 30 seconds. Pick an asset, define a time window, click Run. Full backtest. Full analytics. Full trade history. Zero coding.
